Expert Q&A: Safe Use of Nail Products in 2026

Ekspert Q&A: Sikker brug af negleprodukter i 2026 — safety

Gel polish is a popular and long-lasting way to paint your nails—but it requires proper technique and product selection. Here's expert advice on everything from prep to removal, based on chemistry and best practices.

How Important is Chemistry in UV-Curing Gel?

Very important. Gel polish contains photoinitiators (chemicals that start the polymer chain when UV light hits them), various resins and monomers that give strength and shine. A quality gel is formulated for:

  • Proper polymerization under UV light (not undercured or overcured)
  • Minimal allergenic potential (HEMA-free, TPO-free)
  • Correct viscosity for application—neither too thin nor too thick
  • Good adhesion to the nail surface
  • Long wear time (3-4 weeks without lifting or cracking)

Not all gel brands are equal—cheaper products may contain allergenic chemicals or be poorly formulated, leading to problems like lifting, wrinkling, and brittle nails.

Myths vs. Facts: "Gel Nail Polish" vs. Real Gel Polish

There's a lot of misinformation about gel polish. Let me clarify:

Myth: "Gel nail polish" that air-dries Fact: Gel polish does NOT air-dry—it requires UV light to polymerize. If you buy something called "gel nail polish" but it "air-dries," it's not real gel—it's regular nail polish with gel-like ingredients. Real gel only polymerizes under UV light.

Myth: UV lamps are dangerous Fact: UV lamps for gel polish emit far less radiation than natural sunlight. A 30-60 second exposure is minimal compared to a day at the beach. If you're concerned, apply sunscreen to your hands before treatment.

Myth: Gel polish permanently damages your nails Fact: Gel polish doesn't permanently damage nails, but repeated application and improper removal can weaken them over time. Give your nails breaks between manicures, use HEMA-free products, and remove carefully.

Myth: All gel brands are the same Fact: Quality varies enormously. Professional-grade gel is better formulated and rarely allergenic compared to budget brands. Always choose established brands that prioritize HEMA-free and TPO-free formulations.

Expert Advice: Prep

Question: What's the right way to prep your nails?

Prep is CRUCIAL for long-lasting gel polish. Follow these steps:

  1. File your nails to your desired shape. Use a file with the correct grit (100/180 is good for beginners). Product: The Dual LED Flash SMART UV/LED lamp (39,00 €) for optimal curing.
  2. Remove cuticles carefully—push them back or use a cuticle remover to remove dead skin.
  3. Buff the nail surface lightly to remove shine. This gives better adhesion for the gel.
  4. Cleanse with rubbing alcohol or a dehydrator to remove all oil, moisture, and powder.
  5. Apply a thin layer of base coat and cure under UV light for 30-60 seconds.

Poor prep is the single biggest reason gel polish lifts or doesn't last long. Don't skip these steps!

Expert Advice: Application

Question: How do I apply gel polish correctly?

  1. Apply thin, even layers—not a thick glob. Start from the nail base and stroke toward the tip.
  2. Make sure you cover the entire nail all the way to the cuticle line and edges. Incomplete coverage leads to lifting.
  3. Cure under UV light for 30-60 seconds (or as the package instructs).
  4. Apply 2-3 thin color layers instead of 1-2 thick layers. This gives even coverage and better longevity.
  5. Finish with a top coat layer and cure once more.

Thin layers are key to both longevity and safety. Thick layers don't polymerize properly and generate more heat during curing.

Expert Advice: UV Curing

Question: What should I know about UV curing?

  • Time: Follow the brand's instructions. Usually 30-60 seconds per layer. Not more—it leads to overcuring.
  • Burning sensation: The heat you feel is from the exothermic reaction (chemical process), not the UV radiation. If uncomfortable, apply thin layers or dip your nails partially out of the lamp every 15-20 seconds.
  • Lamp maintenance: UV lamps weaken over time. Replace bulbs every 12-18 months for optimal curing.
  • HEMA-free and TPO-free: Choose gel brands that are HEMA-free and TPO-free for minimal allergy risk.

Expert Advice: Product Selection

Question: Which gel polish should I choose?

Always choose:

  • HEMA-free and TPO-free formulations—less allergy risk
  • Professional-grade gel—better quality than budget brands
  • Known brands with good reviews
  • Gel that suits your nail type—some gel is better for thin nails, others for strong nails

Expert Advice: Removal

Question: What's the safe way to remove gel polish?

  1. Apply oil around your nails—protects skin from acetone irritation.
  2. Soak in acetone (use a special gel-removal kit with acetone) for 10-15 minutes.
  3. Push the gel off slowly with a wooden pusher—never pick or peel it off.
  4. Moisturize your nails after removal with oil or cream.

NEVER: Peel gel polish off with your nails or use a metal scraper—this damages your nails.

Frequently Asked Questions from Experts

How do I know if a gel polish is HEMA-free?

Check the ingredients list on the product label or website. It should explicitly state "HEMA-free" and "TPO-free." All our gel products are HEMA-free and TPO-free.

Is a burning sensation under UV curing normal?

Yes, if it's mild. It's heat from the polymerization process. If you experience strong discomfort, apply thin layers, use a lamp with reduced intensity, or dip your nails out of the lamp every 15-20 seconds.

How long can I keep gel polish on?

Usually 3-4 weeks. After that, it starts to lift and look worn. Some people have it longer, others shorter, depending on nail health, activity level, and product quality.

What is cuticle anatomy, and why does it matter?

Cuticles are a thin layer of skin that overlaps the nail base. They protect and seal the nail. If you push too hard during prep, or if gel polish contacts the cuticle skin, irritation or inflammation can occur. Always be gentle and never apply gel directly to the skin.

Does gel polish last longer than regular nail polish?

Yes, much longer. Regular nail polish typically lasts 5-7 days before chipping or becoming dull, while gel polish lasts 3-4 weeks without chipping or dulling. This is the main reason gel is so popular.

Conclusion

Safe gel polish requires proper product selection, thorough prep, careful application, and safe removal. By following this expert advice and choosing quality products that are HEMA-free and TPO-free, you can achieve beautiful, long-lasting nail color without problems.
